How To Fix Vanguard Error in League of Legends?

Did you come across a Vanguard error in League of Legends and don’t know how to fix it? This guide should help you solve the problem step by step. Here’s our guide on how to fix Vanguard Errors in LoL.

What Is Vanguard and the Errors

Vanguard is a kernel-level anti-cheat tool. The system was implemented by Riot Games first on their FPS title, VALORANT, and its strong success led the dev team to add it to League of Legends as well. What Vanguard essentially does is prevent cheating programs from being used and instantly blocks you from playing the moment it detects one. It’s a very powerful tool, but it can also lead to some errors during use.

The main Vanguard errors that pop up in League of Legends are usually caused by:
